Deoxygenative Reduction of Carbon Dioxide to Methane, Toluene, and Diphenylmethane with [Et₂Al]⁺ as Catalyst

Abstract

The strong Lewis acid [Et(2)Al](+) catalyzes the reduction of carbon dioxide with hydrosilanes under mild conditions to methane. In benzene solution, the side products toluene and diphenylmethane are also obtained through Lewis acid catalyzed benzene alkylation by reaction intermediates.
